timeframe=bt.TimeFrame.Minutes and sleep 3 seconds

New environment, pip freeze:

Trying to use this sample code https://github.com/alpacahq/alpaca-backtrader-api/blob/master/sample/strategy_sma_crossover.py, but with one difference, instead of bt.TimeFrame.Days I am trying bt.TimeFrame.Minutes:

```
data0 = DataFactory(dataname=symbol,
historical=False,
timeframe=bt.TimeFrame.Minutes,
backfill_start=True,
)
```

And looks like forever logging:
